Ludlow, .in the' county of Windsor and State y full,l clear, and exact description. y

of Vermont, vhave invented a new and Improved Separator, of which. the following is a The invention relates to grin g-mills and like reducing-machines for reducingl dry'substances to powder; and its obj ect is'to provide anew and improved separator arranged to insure a thorough and com lete separation j The invention consists of novel featuresv Fig. 3 is an end view of the same.

A practical embodiment of the inventionA is represented in the accompanying drawings,forming a partof this specification, in which similar characters of reference indicate corresponding parts in all the views.:

- The collector A for receivingv the tailings and -thevcollec'tor for receivi the finished productareboth preferably ma e of invertedcone shape, as lplainly illustrated in the drawand the said collectors are -provided at their lower ends withsuitable. dischargeJ devicesAyB for continually discharging they tailings and the finished product. The cllectors A and. B are providedat. their upper ends with heads A2 B2, `of which'the head A2 for the tailings-collector A has the topportion A3 'made approximately'sp'irally and ter' minating at its lower end in a conical portion j A, connectedat its lower end with the cy1indrical ortion A3 on the base of the collector y A. T`e top -head A2 at different portion A3 is' providedwith a plurality of spiral channels -A, all starting from one point'and'openmg sidewlse into the oints of its circumference, as will be readi y understood by referenceto FigfZ. The outlet from each channel A6 intothe head A2"is controlled by' a' lsuitable gatelA7, preferably in the form of a hinged gate adaptedt'o'be opened or closed byithe use of a rod A3, pivotally connected with the gate A7 and extending to the outside ofthe head A2 to allow the operator to take Specification of Letters Patent.

told and manipulate the rod AS with a View to set each gate A7 into the desiredposition. At. the junction of the parts A4 and A5 is arranged an inwardly-eXtending/and slightly upwardly inclined annular deiiector C for deectin'g the tailings and causing the same to dropv over the deflector C down into the collector A.

' 1 The head A2 Vof the tailings-collector A is connected by a pipe D with the head B2 of the finished-product collector B in such a bmanner that the end D of the pipe D eX-` tends centrally into lthe cylindrical portion f A3 of lthe head A2, while the other end D2 of the said pipe extends tangentiallyinto the head B2 at or near the to thereof. Into the starting ends of the spira channels A6 in 'the 4to be treated directly from the grindincemill or other.reducingmachine, the spout" of the said hopper F being provided' with 'a suitable feed-wheel F2 for feeding the material in measured quantities into the dischargelpipe E ofthe fan or blower E.

The operation is as follows: When the Y separator 'is in action, then the blast from the fan orblower E carries the material dropped into the discharge-pipe E from'the hopper F forward into the spiral top A3 of the head A2,- vso that the material is forced through the spiral channels A6 and discharged through the open gates A7 into thehead A2, in which the material 'is whirled around, whereby the tailings separate from the air-blast and the product, and the tailings gradually'v drop or settle in the collector A, while the finished product and air-blast is discharged up by the pipe D and delivered by the latter into the head B2 of the finished-product collector B.

IOC

Now the material as it is discharged into the headBis whirled around therein, as the pipe D2 opens tangentially into the head B2, and theair-blast is sucked up by the pipe E2, which is the inlet or suction pipe for the fan blast produced by the action ci the fan E,`

while the air separated in the head B2 is osucked up by the suction-'pipe E2, which returns the air back tothe fan E after separation has taken place, to be again set'into the lcollector A, Vtogether with a new charge of material delivered'to the pipe E from4 the r'ho per F.

' y the arrangement described a directl`- separation oil the tailings and the material takes place in the head A2 of the tailings-collector A by whirl'ing the material around and 2o ,causing the tailings to drop downpvhile the finished product', together with v the air, is

sucked up` outof thev head by the pipe D,

' which latter'carries thematerial over into the head B2, in which' a like whirlingaction takes z5 placeto insure complete and thorough separation of the inished product from the air,

f whichlatterpasses by'way of the`suctionf ipe 'E2 back to the fan, to be again 'set in the cad Azfor collection in the collector A2, as 3o previously explained.

Y It will further be seen thatiby'the arrangement described thefinished product settles vin the collector B, while the air goes back .to the exhaust-fan E. j By reference to .the drawings it will be 4noted that the pipe ends D" and E3 extend "suiciently far down into the heads A2 and Be'to causeI the blast of air and the material carried'along by the same to whirl around .io the said pipe ends, and hence the heavier tailings in thehead Az are not liable to be sucked up into the'pipe D, and thel finished product `is not liable to besucked .up into the pipe E?. It willalso be noted'that thetailings on gradually dro ping withinthe cylin-l d ric'al portion A3 ii'nalI yreach and slide down the conical portion A* onto the deflector C,

over the inner edge otwhich the, tailings 'linally pass and drop byv their owny weightv `5o`into the collectorA and dischargeco'ntinually therefrom. c 4'It is also understood that the l force of the air-blast in the head A2 issuflicientl'y strong to carry the product along intothe pipe D while the tailings are separated. 5 5 In the head B12 the force of the air-b ast has *l y V the iinished product and the air.

sufficiently diminished to allow separation of claim as new and desire yto secure by Letters gi.
